Cancer expert Dr Cyril Minty warned pot room and other
workers at the Portland
and Point Henry smelters could develop the diseases if they
continued to work in
the same conditions for a long time.

His comments were included in a report in The Sun on May 1,
1989.

The newspaper article sparked demands from Alcoa for a
printed retraction, with
the company saying it "emphatically rejects"
there was any risk of smelter workers
developing cancer because of their working conditions.

This week, the company revealed it had warned 3000 workers
they faced a risk of
cancer from long-term exposure to coal tar pitch, and
arranged mass medical
checks.

The manufacturing giant yesterday denied playing down
potential health dangers,
saying it still had no direct evidence its Australian
workers were at higher risk of
cancer than the general community.

The comments came as lawyers said they were investigating
reports from 50
smelter workers who feared they may have developed cancer
at work.

Maurice Blackburn Cashman partner John Price warned the
industry to brace for
potential compensation claims of millions of dollars if a
cancer time-bomb
exploded.

Company spokesman Brian Wills-Johnson insisted the plants
operated according to
national safety regulations, including the use of
respiratory masks, barrier creams
and routine cleaning of clothes.

Union officials expect to hold urgent meetings with the
company tomorrow.

The Australian Manufacturing Workers Union is demanding
independent, paid
medical checks, newspaper advertisements warning of
potential risks and full
copies of research.

"The calls are coming in thick and fast from
frightened people around Australia,"
union organiser Mark Light said. "We are desperate for
more information."

Alcoa has told thousands of present and former Australian
workers who worked in a
certain section some may face long- term risks of
developing lung and bladder
cancer after a review of overseas research.

A 1995 study found Canadian workers exposed to the coal tar
pitch over 40 years
faced up to 2per cent extra risk of the illnesses.

About 3000 workers who have worked in a section of the
Point Henry and Portland
plants exposed to the substance have been informed of the
potential health
hazard in letters.

Medical checks are expected to begin within weeks.

Alcoa has also ordered stringent new controls worldwide
that limit unprotected
exposure levels to coal tar to a quarter of those required
by Australian occupational
health and safety authorities.

Mr Wills-Johnson said the Canadian Alcan study had been
regarded as a
benchmark and denied the company had been slow to react to
it.

Alcoa's review of the research concluded a small increase
in cancer risk could be
expected at lower levels of exposure than had previously
been accepted.

Mr Wills-Johnson said a medical study of Alcoa staff by
Monash University over the
past three years had not so far shown any excessive rates
of any cancers.

Australian workers had been exposed to much lower levels of
coal tar pitch, a
substance used in part of the smelting process and operated
with more modern
technology than the Canadian site.

But Alcoa had decided to act conservatively by issuing
letters suggesting health
checks for workers who spent at least a year in the
electrode areas of the plants,
he said.

The comments came as unions called for a federal inquiry
into health standards in
the aluminium industry and a further crackdown on exposure
standards.

A spokesman for Mr Reith said occupational health and
safety was largely a state
responsibility but his office would consider submissions
through the National
Occupational Health and Safety Commission.

Martin Jennings, president of the Australian Institute of
Occupational Hygienists,
said Alcoa and other aluminium producers had been
evaluating the dangers for
years
